FAQ

Frequently Asked Questions. Deck & Porch Inspections in St. Louis

How do I know if my deck or porch is structurally unsafe?

Visible wobble, sagging, bouncing, cracking, rot at posts or ledger, deteriorated hardware, or a deck that was never permitted are all reasons to have a structural engineer evaluate the deck before use, especially if it supports a roof or is attached to the house.

My deck was built without a permit. Is that a problem?

Unpermitted decks were built without engineering review or inspection, which means there is no assurance the framing meets code requirements for load capacity, connections, or footing depth. A structural engineering evaluation can assess the current condition and identify what, if anything, needs to be corrected or permitted retroactively.

Does StructSolve provide a written report for deck inspections?

Yes. StructSolve provides a written structural assessment documenting observed conditions, findings, and recommended next steps. PE-stamped documentation is available for qualifying engagements, for permit applications, lender conditions, or insurance purposes.

My home inspection flagged a deck concern. Do I need a structural engineer?

If your home inspector flagged a deck or porch concern, a structural engineer can provide the specific assessment the inspector was pointing toward, evaluating the structural significance of the condition and advising on next steps. This is a common reason St. Louis buyers and homeowners contact StructSolve.

Can StructSolve help with a porch on an older St. Louis home?

Yes. Older St. Louis homes often have front porches with brick piers, aging wood framing, and original connections that have deteriorated over decades. StructSolve evaluates these conditions and provides clear guidance on structural status and needed repairs.
